This article contains a list of animals displaying homosexual behavior. See also Homosexual behavior in animals.

Roy and Silo, two Central Park Zoo male Chinstrap Penguins similar to those pictured, became internationally known when they coupled and later were given an egg that needed hatching and care, which they successfully did.[1]

Selected images

Three species of Cnemidophorus.

The asexual, all-female Whiptail lizard species Cnemidophorus neomexicanus (center), which reproduces via parthenogenesis, is shown flanked by two sexual species having males, C. inornatus (left) and C. tigris (right). Research has shown that simulated mating behavior increases fertility for Cnemidophorus neomexicanus. One female lies on top of another, playing the role of the male, the lizard that was on bottom has larger eggs. The lizards switch off this role each mating season.[2]

The head of a Darner dragonfly (Basiaeschna janata).

Male homosexuality has been inferred in several species of dragonflies. A survey of damsel and dragonflies reveals characteristic cloacal pincher mating damage in 20–80 percent of the males, indicating a fairly high occurrence of sexual coupling between males.[3][4]

Arctic Grayling (Thymallus arcticus) leaping for a fly fisherman's bait. Research going back to the 1950s has shown both male and female Graylings exhibit homosexual behavior.[22]

Male flour beetles are believed by scientists to engage in gay sex to practice mating as well as rid themselves of "old, less effective" sperm.[71]
